Soraa & the Rendering of Whites

There has been big pickup of the story we covered in February: the Penn State study that Soraa sponsored, demonstrating that blue-pumped LED light does not activate the optical brightening agents (OBAs) present in pretty much any product that the manufacturers want to appear whiter than white. We had introduced the topic of OBAs the previous September.

But in the more mainstream tech coverage, Soraa may not be getting its money's worth from the research sponsorship. Soraa's point, of course, is that its violet-pumped LEDs do activate OBAs. In other words, ordinary LEDs cause a problem that heretofore has not been widely discussed, and Soraa has the solution.
